CASL is Canada’s anti-spam legislation and one of the strictest email marketing laws. Learn consent requirements and compliance basics.
CASL (Canada’s Anti-Spam Legislation) regulates commercial electronic messages sent to or from Canada. It is widely regarded as strict because it emphasizes consent and requires clear identification and unsubscribe mechanisms.
Under CASL, many commercial messages require express consent unless an exemption applies. Businesses must also include accurate sender information and a working unsubscribe method. Penalties can be significant, so compliant list building and recordkeeping matter.
If your campaigns touch Canadian recipients, treat CASL as a baseline. Use clear opt-in flows, keep evidence of consent where required, and ensure your templates include the right identification and unsubscribe language.
